Havenask is a large-scale distributed information search engine developed by Alibaba Group, written in C++ and used to power search for services like Taobao and Tmall. It supports realtime search over hundreds of billions of records with millions of QPS/TPS, SQL queries, and a plugin system for customization.
Use cases
- build a large-scale distributed search service
- run realtime full-text search over billions of documents
- query structured data with SQL through a search engine
- self-host a high-performance search engine like Alibaba's
- deploy millisecond-latency search with millions of writes per second
- customize search ranking algorithms with plugins
When to choose
- you need massive-scale, low-latency distributed search with realtime indexing
- you want SQL-based querying over a search engine
- you need a proven engine battle-tested at Alibaba scale
- you want deep customization of search algorithms via plugins
When to avoid
- you need a simple embedded full-text search library for a small app
- your team cannot operate Docker-based distributed infrastructure
- you want a managed search service rather than self-hosting
- you primarily need vector-only semantic search without keyword search
